History Recap / Supergirl2015S5E01EventHorizon

* EverythingsBetterWithDinosaurs: Malefic J'onzz shapeshifts into a T-rex to life to fight Kara.
-->'''Kara:''' Well, this is new and terrible.

* EverythingsBetterWithDinosaurs: Malefic J'onzz brings a T-rex to life to fight Kara.

* RealityEnsues: Kara lampshades that it's much easier to stand up to a woman she dislikes than to risk losing the good opinion of a friend. [[Literature/HarryPotter It takes courage to stand up to one's enemies, but even more to stand up to a friend]].

* ArtisticLicensePhysics: J'onn and Kara should have been immediately disintegrated by the black hole, and Brainy, Nia, and Alex, along with much of the building, should've been sucked in.

** The non-compete agreement that's so important to the dramatic conflict from this episode is actually ''specifically'' unenforceable in the state of California. This fact is frequently cited as being one of the major "secrets" behind the success of Silicon Valley, making tech employees able to switch jobs and share ideas with ease. In real life Andrea also wouldn't be able to give all the reporters 3-year contracts with non-compete clauses without their knowledge or agreement. They would need to knowingly sign them, and something inserted later wouldn't be binding.
** There's mention of a special election for US Senate. While the US House of Representatives, aka the "People's House," would have special elections to fill vacancies, Senate vacancies are filled by the governors of the several states appointing a replacement, who normally serves until the next regular election time.

* ArtisticLicenseLaw: The non-compete agreement that's so important to the dramatic conflict of this episode is actually ''specifically'' unenforceable in the state of California. [[CriticalResearchFailure This fact is frequently cited]] as one of the major "secrets" behind the success of Silicon Valley, making tech employees able to switch jobs and share ideas with ease. It's also unclear how Andrea was able to give all the reporters 3-year contracts with non-compete clauses without their knowledge or agreement.

* ElectionDayEpisode: Kara mentions that the voter registration is down for the "Special Election For Senate." While the House of Representatives, aka the "People's House," would have special elections to fill vacancies, Senate vacancies are filled by the governors of the several states appointing a replacement, who normally serves until the next regular election time.

* FaceHeelTurn: As noted above, while Lena hasn't yet turned fully evil and refuses to see herself as thus, this episode shows that she hates Kara for a perceived betrayal and would have revealed her secret to the world. She only stops when she realises that she can now manipulate Kara to further her own plans. Viewers now know that the Lena of the last few seasons is gone.
* [[IHaveNoSon I Have No Brother]]: J'onn exclaims that he has no brother when Malefic introduces himself. Unlike [[{{Disownment}} most examples]] of this trope, J'onn seems to sincerely have had no idea that he had a brother.
* InsaneTrollLogic: Clearly, Kara's reaction when Andrea claims that her winning a Pulitzer Prize means the paper is ''less'' important to casual readers as it's now "pedantic and dull." Kara openly calls it "insane."

* {{Plot Hole}}: This can apply to Lena's actions up to the Crisis Crossover. Her {{Face Heel Turn}} is based on every person she called a friend or loved, gave betrayed her. She seems to have forgotten Jack did not betray her and neither did Samantha. Also, in season 3, she made it clear to Alex that other people’s secrets are not for another party to reveal. Yet she is angry and hurt because the people that she considered friends, chose not to reveal Kara's secret.

* LameExcuse: How Kara tries to talk her way out of coming clean to Lena towards Alex.

* EverythingsBetterWithDinosaurs: Malefic J'onzz brings a T-rex to live to fight Kara.
* EvilIsPetty: While Lena may not have gone full evil yet, it's clear that her selling [=CatCo=] to Andrea and not telling Kara and James about it was driven by her anger at them keeping Kara's secret from her. That this means the company is transformed into a clickbait tabloid and James loses his job doesn't seem to matter much to Lena.
* Lena plan to out Kara also comes under this. She doesnt seem to care that this will mean all of Kara's family and friends (which ironically would include Lena) would suddenly be put at risk from villains who would either want revenge on Supergirl or leverage against her. This would include ex-employees such as Nia, who Lena is unaware has any powers.
